Effect of Positioning on Oxygenation and Hemodynamics among Patient on Mechanical Ventilation

Abstract

Critically ill patients require regular body position changes to minimize the adverse effects of bed rest, inactivity and immobilization. However, uncertainty surrounds the effectiveness of lateral positioning for improving pulmonary gas exchange, aiding drainage of tracheobronchial secretions and preventing morbidity (Hewitt, et. al, 2016). The positioning of a patient in bed can directly affect respiratory function in mechanically ventilated (MV) patients. In addition to promoting a reduction in the risk of developing pneumonia, some postural positions can increase the possibility of more homogeneous alveolar ventilation and possibly reduce the risk of lung injury caused by mechanical ventilation similar to that in patients undergoing ventilation in the prone position (Martinez, et. al., 2015). Aim of the study: The Present study aimed to: Assess the effect of positioning on oxygenation and
